Abstract
Objective: To explore the effects of enteral immunonutrition support therapy on nutritional metabolism, immune function, and inflammatory response in adult burn patients at nutritional risk as assessed by the modified 2nd nutrition risk screening (NRS) 2002. Methods: A prospective randomized controlled study was conducted. From December 2019 to January 2022, 500 adult patients who were admitted to the Affiliated Huaihai Hospital of Xuzhou Medical University and had nutritional risk assessed by the modified 2nd NRS 2002 were recruited into the study. According to burn severity, the patients were divided into common burn patients (n=450) and severe burn patients (n=50). According to the random number table, the patients with common burn were divided into common burn diet nutrition group and common burn diet enteral immunonutrition group, with 225 patients in each group, and the patients with severe burn were divided into severe burn diet enteral non-immunonutrition group and severe burn diet enteral immunonutrition group, with 25 patients in each group. The patients in each group were given the corresponding nutritional support therapies on the basis of routine burn treatment. On post injury day (PID) 1, 3, 7, 14, and 21, the total energy intake and total protein intake of the patients in 4 groups were recorded, the plasma prealbumin, albumin, transferrin, serum immunoglobulin A (IgA), IgG, IgM, peripheral blood CD3 positive T cell percentage, CD4 positive T cell count, CD8 positive T cell count, the ratio of CD4 positive T cells to CD8 positive T cells, natural killer cell percentage, plasma interleukin-6 (IL-6), free mitochondrial DNA (mtDNA) copy number, and soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) of the patients in 4 groups were detected, and the nitrogen balance of the patients in 4 groups on the day was calculated. On PID 7, 14, and 21, the modified 2nd NRS 2002 scores of the patients in 4 groups were reassessed. The sepsis incidence during treatment and the length of hospital stay of the patients in 4 groups and the length of intensive care unit (ICU) stay of the patients in the 2 severe burn groups were recorded. Data were statistically analyzed with chi-square test, Fisher's exact probability test, Mann-Whitney U test, independent sample t test, analysis of variance for repeated measurement, and Bonferroni correction. Results: A total of 476 patients completed the trial, with 213 patients in common burn diet nutrition group (112 males and 101 females, aged (37±19) years), 218 patients in common burn diet enteral immunonutrition group (115 males and 103 females, aged (42±16) years), 22 patients in severe burn diet enteral non-immunonutrition group (11 males and 11 females, aged (35±8) years), and 23 patients in severe burn diet enteral immunonutrition group (12 males and 11 females, aged (35±8) years).

Abstract
OBJECTIVE To establish a culture system for human nasal mucosal organoids with controllable differentiation to reproduce the structure and function of the source tissue through staged expansion-differentiation culture. METHODS Fresh samples of surgically resected middle turbinate and nasal polyp tissues were collected, from which the nasal mucosa epithelial cells were isolated by enzymatic digestion and filtration for continuous culture at the air-liquid interface for expansion (EO group) or staged culture for expansion and differentiation (DO group). Immunohistochemical staining was used to characterize the structure, cellular composition and ciliary function of nasal mucosal organoids in the two groups. The secretion function of the differentiated nasal mucosal organoids in DO group was evaluated using PAS staining. RESULTS Both of the two organoid culture systems yielded vacuolar or solid spherical 3D organoids, and their diameters increased progressively with time. On day 16 of culture, more vacuolar organoids occurred in DO group, while more solid spherical organoids were seen in EO group, and the proportion of vacuoles was significantly greater in DO group than in EO group [(54.67±13.26)% vs (21.67±8.57)%, P < 0.05]. Short tandem repeat (STR) test of the nasal mucosal organoids and the source tissue showed a 100% match between them. On day 21 of culture, scanning and transmission electron microscopy of the nasal mucosal organoids identified ultrastructure of cilia in DO group and short villi structure in most of the organoids in EO group. Immunohistochemical staining showed positivity for P63 (basal cells), β-tubulin (ciliated columnar cells), and MUC5AC (goblet cells) in the organoids. Compared with those in EO group, the organoids in DO group showed significantly greater percentages of ciliated cells [(7.95±1.81)% vs (27.04±5.91)%, P < 0.05] and goblet cells [(14.46±0.93)% vs (39.85±5.43)%, P < 0.05) with a similar percentage of basal cells [(56.91±14.12)% vs (53.42±15.77)%, P > 0.05]. The differentiated nasal mucosal organoids in DO group were positively stained for glycogen. CONCLUSION The staged expansion-differentiation culture method allows more stable and prolonged growth of the cultured cells in vitro to produce organoids with controllable differentiation closely resembling the morphological structure and functions (ciliary function and secretory function) of the source tissue.

Abstract
BackgroundAbatacept (ABA) has demonstrated efficacy and safety in active rheumatoid arthritis (RA) patients in Europe and the United States as one of bDMARDs [1]. However, the clinical activity of Abatacept (ABA) has not been sufficiently investigated in patients with RA from a real-world clinical setting in China.ObjectivesThis study was designed to investigate the efficacy and safety of Abatacept in the RA patients in Chinese population who were refractory to csDMARDs, aiming to provide further reference for clinical rational drug use.MethodsClinical data of 55 patients with active RA who were admitted in the Affiliated Hospital of North Sichuan Medical College from June 2020 to June 2021 and did not respond to csDMARDs was retrospectively analyzed. Patients in this study were treated with Abatacept (125 mg by subcutaneous injection once weekly combined with csDMARDs. Changes in clinical manifestations, including DAS28-ESR, CDAI, ACR 20/50/70 at week 12 and 24 from baseline and AEs during 24 weeks were observed and recorded.Results55 patients (46 women and 9 men) were included in this study with a mean age 50.80 ± 12.46 and a mean disease duration of 6.29 ± 6.22 years. The ACR 20 response at week 12 and 24 was 50.91% (28/55) and 87.27% (48/55), respectively. Besides, DAS 28-ESR score were significantly lower at week 12 and 24 compared to baseline (P <0.05) with 19 patients (34.55%) achieving clinical remission or low disease activity. Changes in CDAI scores revealed that 80% patients achieved clinical remission or low disease activity at week 24. DAS28-ESR score was significantly lower in previously untreated patients (Biologic-naive) (n=36) (3.40 ± 0.81) than in the previously treated patients (Biologic non-naive) (n=19) (3.83 ± 0.68) (P = 0.02) (Figure 1). RF, CCP antibody and GLOB levels were significantlyreduced in RA patients after 24-week ABA treatment compared to baseline (P﹤0.05) (Table 1). Two hepatitis B virus (HBV) carriers, two patients with active tuberculosis and one patient with latent tuberculosis status showed no reactivation of HBV and no new active tuberculosis lesions 24 weeks after treatment with ABA. AEs were reported in 9.1% (5/55), but no serious infections occurred.Table 1.Analysis of clinical and serological parameters at baseline and after treatment with Abatacept.IndexesBaseline12 weeks24 weeksTJC6 (4,10)3 (2,4)*2 (1,3) **SJC2 (1,4)1 (0,2)*0 (0,1)**PtGA-VAS(0-10cm)8 (7,10)5 (3,6)*2(2,3)**HAQ2 (0,4)1 (0,2)*0 (0,1)**ESR (mm/h)51 (41,89)37 (28,51)*23 (17,37)**HsCRP(mg/L)14.08 (3.7,35.0)5,77 (2.27,20.78) *4.12 (1.34,9.37) **GLOB34.47±5.69-30.33±3.81*RF-IgM (IU/mL)408.55 (68.8,566.5)-167.41 (34.9, 171.25) *RF-IgG (U/mL)8.63 (4.55, 11.1)-7.94 (3.13, 6.23) *RF-IgA (U/mL)90.18 (25.63, 99.12)-58.20 (16.81, 59.09) *CCP (RU/mL)1095.45 (66.79, 1033.28)-782.0 (58.49, 857.5) **p﹤0.05,TJC=Tender joint count, SJC=Swollen joint count, GLOB= immunoglobulin.ConclusionIn the Chinese patients with active RA refractory to csDMARDs, the combination of ABA and csDMARDs showed great clinical efficacy and a favorable safety profile.

Abstract
Objective: To investigate the effectiveness of nucleos(t)ide analogues in the treatment of HBeAg-positive chronic hepatitis B with normal alanine aminotransferase and high level of HBV DNA. Methods: Treatment-naïve chronic hepatitis B patients who were followed up at the Center of Infectious Diseases, West China Hospital of Sichuan University from January 2019 to January 2020 were selected as subjects. Demographic characteristics, the results of laboratory examination before treatment and one year after treatment were retrospectively collected. Patients were divided into tenofovir dipivoxil (TDF) and propofol fumurate tenofovir (TAF) treatment group according to different types of medication. The changes of serum HBV DNA level, HBeAg serological conversion and HBsAg quantitative level were analyzed and compared between the two groups. Results: A total of 38 cases were enrolled. Among them, there were 16 and 22 cases in the TDF and TAF group, respectively. There was no statistically significant difference in demographic characteristics, baseline HBV DNA levels and HBsAg quantitative levels between the two groups. Virological response was achieved in 60.5% (23/38) of patients after one year of antiviral therapy. Serum HBV DNA levels below the lower limit of detection [68.2% (15/22) vs. 50.0% (8/16), P=0.258] and higher HBeAg seroconversion rate [18.2%] (4/22) vs. 6.3% (1/16), P=0.374] was obtained in TAF than TDF group; however, there was no statistically significant differences between the two. Serum HBsAg quantitative level was significantly reduced with TDF and TAF treatment. In addition, alanine aminotransferase elevation was reduced in TAF than TDF treated group. Multivariate logistic regression analysis showed that patient age was an independent predictor of a virological response to antiviral therapy. Conclusion: HBeAg-positive CHB patients with normal alanine aminotransferase, and high HBV DNA level can obtain better curative effect after TDF and TAF treatment.

Abstract
OBJECTIVE To investigate the effects of melatonin on the growth and metastasis of MDA-MB-231 breast cancer cells and explore the mechanism. METHODS MDA-MB-231 cells were treated with 1, 3 or 5 mmol/L melatonin, and the changes in cell proliferation were examined using CCK-8 assay. Colony-forming assay and wound healing assay were used to assess the effects of melatonin treatmnent on colony-forming ability and migration of the cells. Flow cytometry and immunofluoresnce assay were employed to examine apoptosis and positive staining for autophagy-related proteins in the cells treated with 3 mmol/L melatonin. The effects of melatonin treatment alone or in combination with 3-methyladenine (3-MA) on the expressions of the proteins associated with autophagy (LC3, P62 and Beclin1), apoptosis (Bcl2 and Bax) and epithelial-mesenchymal transition (E-cadherin and Snail) were examined with Western blotting. RESULTS Melatonin treatment significantly inhibited the proliferation of breast cancer cells in a concentration- and time-dependent manner (P < 0.05), suppressed colony-forming ability and migration (P < 0.01), and promoted apoptosis of the cells (P < 0.01). Melatonin treatment alone significantly increased the expressions of Bax (P < 0.05), E-cadherin, LC3-II/LC3-I, and Beclin1 and lowered the expressions of Bcl2 (P < 0.05), Snail, P62 (P < 0.05), and Bcl2/Bax ratio (P < 0.01) in the cells, and caused enhanced positive staining of Beclin1 protein and attenuated staining of P62 protein. Compared with melatonin treatment alone, melatonin treatment combined with 3-MA significantly decreased the expressions of Beclin1 (P < 0.001), LC3-II/LC3-I (P < 0.05), Bax (P < 0.01), and E-cadherin (P < 0.001) and increased the expressions of Bcl2 (P < 0.05), Snail, and Bcl2/Bax ratio (P < 0.01). CONCLUSION Melatonin can induce autophagy of MDA-MB-231 breast cancer cells to inhibit cell proliferation and metastasis and promote cell apoptosis, and suppressing autophagy can weaken the inhibitory effect of melatonin on the growth and metastasis of breast cancer cells.

Abstract
Nootropics (smart drugs) are used by students to enhance cognitive performance which have been reported times in recent years. However, some of the nootropics are central nervous system stimulants which are very likely to lead to addiction or complications such as vomiting and dizziness. Are there nootropics that can improve learning behavior while having potential positive effect on health? Here, we reported that Atomoxetine (ATX) has sex-specific effect on prolonging the life span of female Drosophila melanogaster. Further study indicated that ATX enhanced female resistance to heat stress and their vertical climbing ability, but it did decrease the number of eggs laid. ATX increased food-intake and sleep time both of females and males, and significantly reduced the 24h spontaneous activity of females and males. Our results present the sex dimorphic effect of ATX on life span regulation in Drosophila, and support further research on the beneficial role of ATX and the mechanisms in other animal models.

Abstract
Chronic hepatitis B and its related complications seriously endanger the lives and health of our country people. Although the first-line nucleos(t)ide analogs such as entecavir, tenofovir disoproxil fumarate and tenofovir alafenamide fumarate can inhibit virus replication to a certain extent, delay or prevent disease progression, and reduce the incidence of hepatitis B-related liver cancer, but in clinical practice, HBV DNA positivity is still detected continuously or intermittently in the serum of some patients. Therefore, low-level viremia has received widespread attention and triggered discussion, and has become the difficulties and hotspot of antiviral treatment of chronic hepatitis B. This article summarizes and discusses the definition and incidence in line with the main guidelines and studies, impact of disease control and clinical prognosis, and the current treatment options in order to provide definite reference for the management of low-level viremia during antiviral therapy in patients with chronic hepatitis B.

Abstract
We report a new optofluidic resonating phenomenon that naturally links the optical radiation pressure, total internal reflection, capillary wave, and Rayleigh-Plateau instability together. When a transparent liquid jet is radiated by a focused continuous wave laser beam, the highly ordered periodic jet breakup is unexpectedly triggered and maintained. The capillary wave enables the liquid-gas interface to serve as a rotating mirror reflecting the laser beam in a wide range of angles, including the critical angle for total internal reflection. The liquid jet acts as an optical waveguide to periodically transmit the laser beam to the upstream of the jet. The periodic optical beam transmittance inside the liquid jet exerts time-dependent optical pressure to the jet that triggers the Rayleigh-Plateau instability. The jet breakup process locks in at the frequency corresponding to the peak growth rate of the Rayleigh-Plateau instability of the liquid jet, which agrees with the prediction from the dispersion relation of a traveling liquid jet.

Abstract
Objective: To explore the role and molecular mechanism of hepatocyte nuclear factor 4γ (HNF4γ) in proliferation and stemness of gastric cancer. Methods: A total of 102 cases of paraffin-embedded gastric cancer tissues and matched adjacent gastric tissues and 42 cases of fresh-frozen tissues derived from gastric patients who received radical gastrectomy were collected from the First Affiliated Hospital of Zhengzhou University between 2012 to 2015. The expression of HNF4γ was tested by immunohistochemical staining, quantitative real-time polymerase chain reaction (qRT-PCR). HNF4γ overexpressed (AGS-HNF4γ) and shRNA silenced (HGC27-shHNF4γ) gastric cell lines were established. The effects of HNF4γ on cell proliferation and stemness were verified by XTT, clone formation and sphere formation assay. The expression of CD44 was detected by western blot. Results: The mRNA expression level of HNF4γ in fresh-frozen gastric cancer tissue was (12.43±2.702), which was significantly higher than (3.639±1.109) in normal tissue (P<0.001). The high protein expression rate of HNF4γ in paraffin-embedded gastric cancer tissues was 41.2% (42/102), which was significantly higher than 8.8% (9/102) in normal gastric mucosa tissue (P< 0.001). The protein expression of HNF4γ was closely related to the tumor differentiation, infiltration depth, lymph node metastasis and tumor stage (P<0.05). The median survival interval of patients with HNF4γ high expression was 25 months, the 3-year survival rate was 4.8% (2/42), significantly lower than 38 months and 51.7% (31/60) of patients with normal HNF4γ expression (P<0.001). The proliferation and CD44 protein expression of AGS-HNF4γ cells were significantly higher than those of the AGS-Vector cells. The number of clone formation, sphere formation rate of AGS-HNF4γ cells were 243.5±24.5 and (83.5±3.9)%, significantly higher than 81.0±16.0 and (21.8±5.6)% of AGS-Vector cells (P=0.030 and P=0.010, respectively). The proliferation and CD44 protein expression of HGC27-shHNF4 cells were significantly lower than those of the HGC27-vector cells. The number of clone formation, sphere formation rate of HGC27-shHNF4 cells were 26.0±1.0 and (20.8±8.4)%, significantly higher than 83.5±4.5 and (72.5±4.8)% of HGC27-vector cells (P=0.006 and P=0.030, respectively). Conclusions: HNF4γ is upregulated in the gastric cancer tissues and related with the poor prognosis of patients with gastric cancer. Overexpression of HNF4γ promotes the proliferation and remains the stemness of gastric cancer cells by upregulating the expression of CD44.

Abstract
A detailed study of poly-para-phenylene (PPP) obtained by light-assisted on-surface-synthesis (OSS) on Ag(100) was carried out by scanning tunneling microscopy and spectroscopy together with density functional theory calculations. The use of light in combination with heat allows to lower by 50 K annealing temperature the each stage of the Ullmann coupling. Debromination of the 4,4″ dibromo-p-terphenyl precursors was thus realized at 300 K, the formation of the first oligomers from the organometallic intermediate by silver bridging atom release at 423 K and PPP by complete elimination of the silver at 473 K. This approach to lower the reaction temperature permits to enhance the Ag(100) surface reactivity to become comparable to that of Cu(111). The underlying mechanism of light effect was proposed to occur via surface mediated excitation, with the creation of photoexcited electrons known as hot electrons correlated with surface plasmon excitation. This original pathway combining both light and heat provides an additional parameter to control OSS by separating the precursor activation stage from the diffusion.

Abstract
The thyroid gland is the largest endocrine gland in the human body, which mainly secretes thyroid hormones. Thyroid hormone acts on almost all tissues and cells at different level regulating growth and development, metabolism and other functional activities of the body. Therefore, abnormal thyroid function can affect the multiple organs throughout the body. Liver, as the largest biochemical plant in the whole body, is widely regulated by thyroid hormones, and is one of the important target organs of the thyroid gland. Hyperthyroidism (HT for short) is a common disease of the endocrine system, which can cause liver injury, such as hepatomegaly, abnormal liver function, jaundice, cirrhosis, and liver failure. This phenomenon is also known as hyperthyroidism-induced liver injury, and it is more common in new or untreated or improperly treated patients with hyperthyroidism. The basic liver function test at the beginning of antithyroid drugs (ATD) treatment can clarify the degree of liver injury caused by hyperthyroidism itself, and further predict the additional liver injury with ATD therapy initiation. The core of treating hyperthyroidism-induced liver injury is to rapidly control hyperthyroidism, and restore normal liver function. This review briefly summarizes the incidence rate, possible mechanisms, pathological changes, clinical manifestations, laboratory, imaging and pathologic findings, and the recent advances in diagnosis and treatment of the hyperthyroidism-induced liver injury.

Abstract
Objective: To establish the norm of the Chinese version of Karitane Parenting Confidence Scale (KPCS) in urban areas of China. Methods: From August to December 2017, the parents of 2 216 children (<36 months old) were selected from 15 cities (Beijing, Lianyungang, Hangzhou, Chengdu, Xi'an, Guangzhou, Changsha, Jinan, Guiyang, Ningbo, Dalian, Qinhuangdao, Maanshan, Chongqing and Wuhan) in 14 provinces by stratified random sampling. The general demographic characteristics and parents' parenting confidence were collected by a self-made questionnaire and KPCS Chinese version. The percentile norm was established. P3, P10 and P25 were used as the criteria to define the degree of lack of parenting confidence. Results: The age of mothers was (30.67±4.29). The age of the father was (32.50±4.99) years old. There were 726 (32.76%), 759 (34.25%) and 731 (32.99%) infants in 6-12, 12-23 and 24-35 months old groups. The total scores of P50, P25, P10 and P3 of KPCS (Chinese version) of infant parents in urban areas in China were 41, 38, 33, and 29 respectively. When the scores of parents were 34-37, 30-33, and ≤ 29, they were judged as mild, moderate, and severe lack of parenting confidence. There was no significant difference in the Chinese version of KPCS between parents of different age groups and parents of different gender (χ²=3.53, P=0.171; χ²=1.41, P=0.236). Each factor score≤P3 is defined as the boundary score, and the corresponding boundary scores of "parenting" "support" and "competence" were 13, 9, and 5 respectively. Conclusion: The Chinese version of KPCS can be used to assess the parenting confidence of infants in urban areas of China. It can used as one of the bases for scientific and objective evaluation of the parenting status of families.

Abstract
Objective: To observe the effects of intensive insulin therapy combined with glutamine on nutritional metabolism, inflammatory response, and hemodynamics in severe burn patients. Methods: Thirty-two severe burn patients who met the inclusion criteria and hospitalized in the Affiliated Huaihai Hospital of Xuzhou Medical University from June 2017 to January 2019 were recruited into a prospectively randomized controlled study. According to the random number table, the patients were divided into conventional insulin therapy alone group, conventional insulin therapy+glutamine group, intensive insulin therapy alone group, and intensive insulin therapy+glutamine group, with 8 patients in each group, with genders of 5 males and 3 females, 4 males and 4 females, 3 males and 5 females, 4 males and 4 females, and ages of (35±7), (36±9), (33±11), and (38±7) years, respectively. Patients in conventional insulin therapy alone group were treated with conventional insulin therapy on the basis of routine treatment to control the blood glucose. Patients in conventional insulin therapy+glutamine group were supplemented with alanyl-glutamine for more than 14 days in addition to the treatment in conventional insulin therapy alone group. Patients in intensive insulin therapy alone group were treated with intensive insulin therapy on the basis of routine treatment to control the blood glucose. Patients in intensive insulin therapy+glutamine group were supplemented with alanyl-glutamine in addition to the treatment in intensive insulin therapy alone group. On treatment day (TD) 1, 3, 7, and 14, the blood glucose, albumin, prealbumin, white blood cell count, procalcitonin (PCT), and C-reactive protein (CRP) of patients in the 4 groups were detected. The cardiac index (CI), stroke volume index (SVI), global end-diastolic volume index (GEDVI), systemic vascular resistance index (SVRI), extravascular lung water index (EVLWI), and pulmonary vascular permeability index (PVPI) of patients in the 4 groups on TD 1, 3, and 7 were measured. Data were statistically analyzed with Fisher's exact probability test, one-way analysis of variance, analysis of variance for repeated measurement, and Bonferroni method. Results: All patients in the 4 groups successfully completed the study, and there were no withdrawal cases. On TD 3, 7, and 14, the blood glucose of patients in intensive insulin therapy alone group ((5.9±1.3), (5.8±0.6), (5.5±0.5) mmol/L) and intensive insulin therapy+glutamine group ((5.9±1.1), (5.6±1.1), (5.2±0.8) mmol/L) were significantly lower than those in conventional insulin therapy alone group ((9.1±0.5), (8.4±0.9), (7.4±1.1) mmol/L, P<0.05). Compared with those in conventional insulin therapy alone group, the levels of albumin of patients in conventional insulin therapy+glutamine group, intensive insulin therapy alone group, and intensive insulin therapy+glutamine group were significantly increased on TD 7 and 14 (P<0.05). Compared with the level of albumin of patients in intensive insulin therapy+glutamine group, the levels of albumin of patients in conventional insulin therapy+glutamine group and intensive insulin therapy alone group were significantly decreased on TD 14 (P<0.05). Compared with those in conventional insulin therapy alone group, the levels of prealbumin of patients in conventional insulin therapy+glutamine group and intensive insulin therapy alone group were significantly increased on TD 7 and 14 (P<0.05). Compared with those in intensive insulin therapy+glutamine group, the levels of prealbumin of patients in intensive insulin therapy alone group and conventional insulin therapy+glutamine group were significantly decreased on TD 1, 7, and 14 (P<0.05). There were no statistically significant differences in the white blood cell count, PCT, and CRP of patients in the 4 groups in pairwise comparison between groups on TD 1, 3, 7, and 14 (P>0.05). On TD 3 and 7, the levels of cardiac index, SVI, GEDVI, and SVRI of patients in intensive insulin therapy+glutamine group were significantly higher than those in conventional insulin therapy alone group (P<0.05), while the levels of EVLWI and PVPI were significantly lower than those in conventional insulin therapy alone group (P<0.05). Conclusions: Glutamine combined with intensive insulin therapy can improve the hypermetabolism in patients after severe burns, reduce the decomposition and consumption of endogenous nutrient substrates, and at the same time help the recovery of cardiac function and maintenance of hemodynamic stability.

Abstract
OBJECTIVE This study aimed to investigate whether percutaneous vertebral augmentation (PVA) was associated with clinical and radiological subsequent adjacent fractures in patients with osteoporotic vertebral compression fractures. MATERIALS AND METHODS The systematic review was performed following PRISMA guidelines. Data were retrieved from PubMed, EMBASE, Cochrane Library, Google Scholar, Web of Science, and ClinicalTrial.gov, from database inception to March 2020. Eligible studies were those that assessed subsequent adjacent fractures after PVA in comparison with conservative treatment (CT). The number of patients with adjacent secondary vertebral fractures was calculated, and the pooled risk ratio (RR) with its 95% confidence intervals (95% CI) was used. Moreover, heterogeneity, sensitivity, and publication bias analyses were performed. RESULTS Twenty-four studies were included finally. Moreover, 20/421 (4.75%) patients from the PVA group and 25/359 (6.96%) patients from the CT group had clinical subsequent adjacent fractures, and 46/440 (10.45%) patients from the PVA group and 36/444 (8.10%) patients from the CT group had radiological subsequent adjacent fractures. Both had no significant difference between the two groups (RR = 0.67, 95% CI [0.38, 1.19], p = 0.17)/(RR = 1.13, 95% CI [0.75, 1.70], p = 0.576). However, the number of fractured vertebrae was higher in the PVA group than in the CT group (RR = 1.41, 95% CI [1.03, 1.93], p = 0.03). A sensitivity analysis did not identify specific trials that seriously deflected. No obvious publication bias was identified. CONCLUSIONS The systematic review revealed that PVA did not increase the incidence for subsequent adjacent fractures regardless of whether they were clinical or radiological fractures. However, PVA can increase the number of subsequent fractures at adjacent vertebral levels.

Abstract
The Tympanic Membrane (TM) transforms acoustic energy to ossicular vibration. The shape and the displacement of the TM play an important role in this process. We developed a High-speed Digital Holography (HDH) system to measure the shape and transient displacements of the TM induced by acoustic clicks. The displacements were further normalized by the measured shape to derive surface normal displacements at over 100,000 points on the TM surface. Frequency and impulse response analyses were performed at each TM point, which enable us to describe 2D surface maps of four new TM mechanical parameters. From frequency domain analyses, we describe the (i) dominant frequencies of the displacement per sound pressure based on Frequency Response Function (FRF) at each surface point. From time domain analyses, we describe the (ii) rising time, (iii) exponential decay time, and the (iv) root-mean-square (rms) displacement of the TM based on Impulse Response Function (IRF) at each surface point. The resultant 2D maps show that a majority of the TM surface has a dominant frequency of around 1.5 kHz. The rising times suggest that much of the TM surface is set into motion within 50 µs of an impulsive stimulus. The maps of the exponential decay time of the IRF illustrate spatial variations in damping, the least known TM mechanical property. The damping ratios at locations with varied dominant frequencies are quantified and compared.

Abstract
Background:Treat-to-target (T2T) approach is recommended as a standard management strategy in rheumatoid arthritis (RA) treatment by Chinese guideline for diagnosis and treatment of RA[1]. However, there is little known about its current implementation in China.Objectives:This study aimed to evaluate the implementation and achievement of T2T approach and explore their associated factors in Chinese RA cohort.Methods:A comprehensive cross-sectional survey of rheumatologists and their RA patients was conducted in China. Data were collected during May-Aug 2019 via physician-completed patient record forms. 60 rheumatologists provided data on demographic, clinical characteristics, treatments, and T2T approach implementation for 600 RA patients. Two logistic regressions were used to evaluate factors associated with T2T approach implementation and T2T goal achievement, respectively. Patients with missing data were not included in the models.Results:600 patients were included in this study (48.8±11.7 years, 70.3% female). 39.0% (N=234) of 600 patients were being treated with T2T approach, and 64.9% (N=366) of 564 patients had achieved T2T goal. Patients with longer disease duration (>2 years diagnosis) (odds ratio (OR) [95%CI]=1.61 [1.05, 2.49], vs. diagnosis ≤2 years), higher pain score (OR [95%CI]=1.26 [1.04, 1.51]), or receiving advanced therapy (OR [95%CI]=6.91 [3.64, 13.13]) were more likely to use T2T. Patients with BMI >23.9kg/m2 (OR [95%CI]=2.83 [1.59, 5.04], vs. BMI≤23.9kg/m2), or who worked full-time (OR [95%CI]=2.12 [1.26, 3.57]) were more likely to achieve T2T goal, while patients with more pain (OR [95%CI]=0.77 [0.64, 0.92]) were less likely to achieve T2T goal.Conclusion:Low implementation of T2T approach is observed in Chinese RA treatment. Longer disease duration, more pain, and receiving advanced therapy are associated with higher probability of T2T use, while higher BMI, full-time work and less pain are associated with higher probability of T2T goal achievement. Standard diagnosis and treatment according to guidelines may improve T2T approach implementation.References:[1]Association, C.R., 2018 Chinese guideline for the diagnosis and treatment of rheumatoid arthritis.

Abstract
Immune checkpoint inhibitors (ICIs) are a recent breakthrough in antitumor drugs, although their overall safety has not been fully defined. Compared to conventional chemotherapy, ICIs exhibit different patterns of immunotoxicity, and immune-related adverse events (irAEs) have an immunological basis that is more toxic than usual and have a broad spectrum of manifestations involving different organ systems. Early recognition of symptoms and timely intervention are very important in managing immune-related adverse events (irAEs). In this study, we report a case of delayed immune thrombocytopenia in a patient treated with nivolumab for small cell lung cancer (SCLC). We found that thrombocytopenia was associated with the presence of platelet antibodies, autoantibodies, and thyroglobulin antibodies, accompanied by a decrease in the number of helper T cells and regulatory T cells. Platelets returned to normal after the removal of antibodies by plasma exchanges and methylprednisolone. We hypothesized that thrombocytopenia in patients was an antibody-driven and T-cell-mediated process. Although these observations indirectly suggest that cytokine changes contribute to immune dysregulation during irAE, prospective validation is needed to explain the confounding etiologies that may contribute to cytokine dysregulation. Therefore, studying the relationship between T cell subpopulations, cytokines and irAE in a larger population may be crucial for identifying biomarkers for ICI.
